Application sied september 25A, 192212 saprai No. 590,458.

To all whom t may concern.' Beit known that I, ETTORE PARISI, manu-v facturer, a subjectr of the King of Italy, andresiding at Rome, Italy A(whose post-oliee address is No. l7 Via Pianel-lari,- Rome,- Italy), have inven-ted certain new 'a-'ndnse-I ful Improvements in Automaticf"Fans,'=of which the following 'is a specification.`

-This'invention relates to fansadapted to be operated either by electricity or by means' of a suitable clockwork mechanism.

Known fans of this kind comprise a'number of fan blades'radially arrangedaround a shaft adapted to beV given a'rotary loscillating movement by clockwork or other driving means through a chain of spur wheels the last of which 'is provided with a crank pin and connecting link imparting reciprocating movement to a toothed rack in mesh with a pinion on said shaft.

The fan or the like according to the present invention comprises a suitable mounting or casing in which are mounted two ory more fan blades radially arranged and having a to-and-fro movement after the manner of a fan, the movements of one part of them being in a horizontal direction and the movements of the other part being in a vertical direction. By using this device, a slight whirling motion of the air vis produced, causing no discomfort but which notwithstanding suiices to refresh the ambient air.

As will hereinafter be seen, the form and outer ornamental design of the fan may be of any suitable or desired type; it should be taken into account that the device in accordance with this invention has not been designed for producing heavy air currents which is the object aimed at in connection with the well known rotary air fans, but is only destined to cause a constant and agreeable moti'on of the air in all directions, causing no discomfort to the user when coming from a short distance, as for instance, when the fan is placed at the center of the table during eating.

For the better understanding of this description, illustrative detailed drawings have been annexed thereto, wherein Figure 1 is a sectional view of a ventilating apparatus constructed in accordance with this invention.

Figure 2 is an upper plan View illustrating the manner of arranging the rods or links which connect the-paddles to the op-4 erating-device.

' In*said-drawings, lindicates a' hollow cas# ing ofany suitable material, form and outer ornamental design, Vinv the interior of which is conveniently arranged an electric mot-or 2,- or a'suit'able clock work. l

The motor lshaftl is provided at -its end with aVwor'm 3 which operates the worm wheel 4, mounted to rotate on the standard 5y and the aXle of which is provided with the cranks 6 and4 7. f v

"The 'former -offsaid cranks operates in a vertical direction the forked rod- 8 provided at its end with a horizontal slot 9 and which by means of suitable links operates the paddles 10 arranged to move on the points 1l and 12, respectively.

The crank 7 operates the rod 13, provided at its end with a vertical slot yor opening 14 and centered at 15; this rod, by means of its upper forked part operates with its ends the paddles 16, mounted to oscillate in a horizontal direction on the points 17 and 17.

From an inspection of the drawings it will be readily understood that after starting the motor or driving mechanism, the action of the cranks 6 and 7 in the slots 9 and 14 will cause the movement of the respective rods 8 and 13 which in turn transmit their motion to the paddles 10 and 16.

In the accompanying drawings, a ventilator is shown whose paddles are operated two in a vertical and two in a horizontal direction, but it will be evident that the same means may also be arranged so as to operate the conjoint of the paddles all in the same direction.

The form of construction above described, may be varied by providing an additional wheel, similar to the worm wheel 4, and causing each paddle to be operated by its own connecting rod.

lThe particular embodiment shown in Figs. 1-4 of the drawings, owing to its proportions, is adapted for use on the table; when it is desired to adopt the apparatus for use near a bed, writing desk, sofa or the like, it may be constructed of greater height, by using eXtensible leads and telescoping supports, mounted yon wheels.

The rod, instead of being operated by means of the slot or slide, may also be acted upon by a simple connecting rod with the necessary links.

The ventilator may consist of two, four or morerpaddlesyof convenient size and theform` of the @enjoint may b chosen aol cordance with the conditions of use. y

By means of the mechanism above described, the paddles are'operzafted-ifn aira'hr' similar to the movement impartedv by al, person to a fan and the air current prlicd thereby, is projected towards wthe contour of the table, being evenly distribted among theI parties occupying thev same. A---urthe advantage of the ventilator inaccopdafnce; With my invention;- cqnsists that there is no r-sk- 'of its paddles becoming, detached non @l1 a person hurting himself on approach-I ingr` his hand,` as is the saine case Wt'zhcentrifugalventilator-sf oi usual@ construction.

Theembodimentshown' inv Fig; 5 is of the type used for bedste'agls, tables',vv setteeslor similar articles and has a ventilator plural uses. Inl the said igure the stanjdard l is adapted to be moved on rolls on" ground and; to enclose the* dpiving'mgechanism.
